Syracuse, in uthe county ot Onondaga, in the Stateof New Yfork, have invented nen7 and use't'ul Improvements in Garnett Machines, of .which the following, taken lin connection ivitli 4the accompanying drawings, is a full,

clear` `and exa/:t description.

`This invention relates to certain improvements in `Garnett machines.

The primary object of the invention is to provide yautonfiatically operating `means for controlling rthe supply of the raw material, such as cotton, wool, etc., .tosucli machine in accru-dance with the needs of the machine, and more specificallyan intermittent feed by means of which `a substantially predeterinincd .amount `ot the raw Ynfiaterial is supplied tothe machine at each feeding operation, suclra feeding operationbei-ng initiate@` at a substantially predetermined `interval of consumption ot the i'aiv material by the machine. i

By this apparatus ,an operating supply ot raw material -is always maintained in the liopperotthe machine .by reason ofitlie fact that the .feed is controlled bythe presence or absence of `a `substantially predetermined aniount-oi'iraw Vmaterial in the hopper of the machine, Manual feeding of the machine is entirely `eliminated by the apparatus of this invention, not yonly assuring Acontinuous .operation oi the xmachine., abutetfefting amate rial saving in the/expense of operation.

Other objects and advantages relate to the details of the apparatus, all `as Will more fully; appear .from the 'following description. taken in `connection -With the accompanying drawings in ,which Figure 1 is anelevation, partially broken away/,oit an apparatus ofmy invention.

The hopper @-1- iojf :the imacliine of this invention :is formed iin 'two relatively -mova Able sections .or with ,1a movable .Wall preferably substantiallyasshomn, thesection=-1f-. being stationary with the finachine, While ithe section -2 :is `pivoted l.on bolts .-3- Eat opposite sides of the stationary section -l-. and at :the lower ,end :thereof for trelative rtilting `movement avith respect :to vrthe section l* as toont-rolled Eby bolts 4mprojecting vinwardly ifrom opposite sides oi the upper portion offzthe section -lvf-i-a-ntl positioned respectively in fthe slots w25- formed inthe upper portion yOffthe movable section Q. The `slots i5- may be formed upon an are 1.which ilias .forits radius Aa lstraight line connecting the axis iof the bolts -8- and l-, .For .the `'purpose ``of .normally maintaining thesection 2vinfits retracted positionpa bell crank.lever-6.is provided at .opposite sides K.ot the :machine pivoted upon Aagbolt or stud J- :mounted ftratethsothat rocking of theebell crank leve-r inner and louter :position as limited by slots m-5--- movinggonzthefbolts 44.- and forethe :purpose ,of :normally holding the section .of such 1leveialoeing;connectedby:a link-Q A -Ql-fin retracted position, a weighty-89- i910 is provided mounted upon the forward end rof ztlie vbell `crank lever 6 :and .preferably `adjustable thereon so hthat the section .-9 can `be maintained in retracted position with the ,degree ,of force `des`iied,fand :this 4for ythe i reason Ithat `the operation of .the `movable Wall or section 2-1ofithelhopperxis adapted to be effected 'by fthe .Weight -of the iraw material, sucli as Oottonor f wool supplied ito the hopper, `and it :may -be desirable 4ito restrain the movement of the section A -2- 5to permit A.the hopper to yfill -to varioustextents to meet various conditions, and thiscan i'be effected :by adjusting Ithe -weight B9-9.

Any suitable `means Efor ,supplying raw material :to ithe :hopper 1- under `the control of mechanism such :as that thereinafter described lmay `be utilized, butlithe ipreferred form o'f `my `invention includes a `continuously moving belt conveyor 110- to which sufhcient rraw material is at all times supplied, softhat therei's raw material enough moving at all'times across the valve. .1l-

the 4.belt-conveyor and the chute lo'rv conduit -13- adapted to convey a raw materialk when suppliedvthereto to the hopmunication betweenthe housing 12- and the chute -13- is controlled, as before sugegested, 'by the .valve .l'l.- which is normally maintained in closed position by the *lever 14.- which carriesthe valve, such leverincluding means, as the weight -15-- for normally overbalancing the valve, and holding it in closed position to cut olf communicationbetween the housing 12--- and 'fthe Achute -13-. ,As shown, the belt-con-r veying. mechanism may bek arranged. upon one floor; of a building, while the Garnett machineisarranged on another floor, as for instance, a lower-floor, and the chute Z'-l3-- may extend through the floor for supplying raw material to the Garnett machine by gravity feed.

AMeans `is provided for opening the valve 115-against the action of the weight f-l5 when the raw material in the hopper -1- has kbeen-consumed orA taken up by the Garnett machine toga substantially predetermined -extent, and this means includes, as illustrated, a flexible cable -16- connected at one end to lever -14-- and at its other end by linl; .-l to therim of the mutilated gear `+l8-. '.Thisv gear .-1O--, asl illustrated, has tWOsegmental portions formed with. gear teeth separated by -two substantially diametrically disposed portions .-19m and -2O--A that are not equipped with gear-teeth, so that when the portion` 19,- is moved to the position shown in Figure 6,-no further rotation of the gear -'-l8--v willtake place" until the effected until tooth s23- is fmoved forfwardly a'sutlicient distance so as to be brought into mesh' w1th the lteeth of; the

rlhe operationof the gear -18-, so as to effect a.y rotary movement of that gear to bring the tooth Q1- and the tooth Q3- intermittently into mesh with gear -22-. is elfected as before indicated by movement of the movable section 2f of the hopper as effected by gravity of the raw material inthe hopper. As described, normally the The lower end of this `"ratchet -24- isformed with a notch preferably substantially as illustrated in Figure 6, which engages the pin or tooth -26-, which extends axially from the rim of the gear -l8-. The notch -27- is of such form that it will operate to rotate the gear in a counter clock-wise direction in Figure 6, but is formed with an elongated inclined surface which will permit the continued rotation of the gear '-18- when the tooth -21- has been brought into mesh with the gear -22-, the pin -26- moving along the cam surface of the notch -27- and forcing the pawl 9A-- outwardly to permit the passage of the pins -26-- This rotary movement of the gear con'- tinues through substantially 180 deg. and

until the untoothed portion is movedk opposite the gear'-22-,` at Which time the pin -2G- will seat itself in the notch k 28- in a second pawl -29-, preferably the notch Q8- is of substantially the. same form as the notch -27-- It will be noted that by this rotary movement liust described the valve -llis opened and raw material will be fed to the hopper. The Weight ofl such material in the hopper vwill gradually tilt :the-section -2- outwardly raising the weighted end `oi .the bell crank lever --f, and thereby :raising the ipaivl -29- `:pivoted on the ,-pin *25T in like `manner as the `p'a-Wl -214-2 rThis raising movement of paWl -29- vvhich engages the pin -2-7-avill bring zthe tooth 4intocmesh with the lgear `--22- when a suicient Weight-oi raw materialhas been received ein theshopper to move the section "2- tosubstantially-the limit-of its expansibleposition, and at that point another `rotation oi the fgearU-IS through substantially-l deg. `Will be effected to again bring the link -l7- 'to positionshovvn 1n Figure 6 Vand permit pthe closing of .the valve .-ll--by gravity movement of Weight -15. For the purpose kof holding lthe paivls -29- in proper relation 1to l.engage pin -26- and yet :to permlt some spreading action, whereby Athe notches y1n the pawls are disengaged with the pin E26-,

the two pawls :are extended `downwardly through a guide rplate -`-30 lwhich maybe secured -to the stationary ysection of thehopper, and is formed with tvvo slotsf-Bl" and -3 the slot -3-1- receiving the pawvl -29w `and the ,slot -82- receiving the paivl Q4-f, the slots Ibeing ofsomewhat greater lengththan the vvidthof the gpavvls, and .for the .purpose of holding .the Apavvls resiliently in engagement With the 'pin -26- in :its respective positions, la coil spring'v -38- `is lprovided preferably 'positioned below the plate -30- and connecting the adjacent portions of the vpavvls 24.- and -29, Yfor drawing them `toward eachother, but permitting .their separation under the camming action of the pin -QG-acting on the Wall-oi Vthe notch 2T-.or ythe Wall of notch .28-1

The operation `of the .apparatus yWill be understood from the above description, the essential features of the Astructure ,being .a

movable Wall or section fin connection with al hopper which by its movement dependent upon the vWeightofthe ravv material in the hopper, controls the feed of raw material to the hopper, and altho I have shown and described a specic construction as illustrative of an embodiment of my invention, I do not desire to limit myself to the details of construction, form, or arrangement of the same, as various changes may be made without departing from the invention as set forth in the appended claims.
